--------------------------------- Led holes in Push button --------------------------------- 1. drill a hole using the drill press. In my case, I didn't have a 5mm bit, so I used a 3/16in bit, which is equivalent to 4.76mm (slightly smaller than the led diameter) There you go! 2.Adjust the hole diameter. Next step, I used a file to adjust the hole size to fit the led. 3. Test fit the LED. Finally, I test fit the led to make sure they can be inserted without too much pressure. --------------------------------- Installing T-nuts --------------------------------- Since my joystick are bottom mounted, I used T-nuts to secure the joystick into place. 1. Use a spade bit to recess the t-nuts 2. Drill the screw hole, big enough for the t-nut to fit. 3. Using a hammer, gently insert the t-nuts in the hole. (t-nuts have some sharp shape used to secure the t-nuts in the wood) !!! put something to support the joystick base recessed section !!! 4. flip the CP over and install the joysticks In my case, I forgot to "support" the recess section of the joystick and it seems that I didn't insert the t-nuts gently... As you can see in this picture, the mdf didn't like the hammer... The mdf still feel solid enough, but I didn't want to take any chance, so I added some additional support (aluminum bracket). It doesn't look as good, but we don't really see that part... 5. Your joystick are mounted! Jay :cheers: |

--------------------------------- CP overlay --------------------------------- Woooo! the scrary part : cutting the overlay. 1. setup your working surface. If you work on the dining room table, make sure you have something to protect it, or the wife will kill you. You will need an utility knife or exacto. 2. Cut the holes. Wash your hands to make sure you don't have anything that can mess your overlay. Using the exacto, carefully cut the holes for the trackball/buttons/joysticks. 3. Install the overlay on the CP. Install the overlay/plexi on the box. Make sure it is aligned with the PC and plexi holes. 4. Trim the overlay. Using a sharp exacto, insert it through your overlay (ouch). Then, let the plexi guide the blade and trim the overlay. 5. Install the T-molding. Using a mallet, insert the t-mold around the CP. In my case, I didn't have a mallet, but some sort of hammer adaptors. These transform any hammer into a mallet. You even have choices for the softness/hardness. Here's another shot with the mallet adaptor installed... 6. Install the push buttons. This is simple enough. You just drop the push button in the hole and secure it with the plastic nuts. the only thing you have to think of is how you orient your button to have room for the wiring of the switches/leds. 7. See how it looks! All right, now flip that thing over, drop the joystick handle into the holes and take a look. another view... Jay :cheers: |

--------------------------------- Illuminated push button labels --------------------------------- for the push button labels, I basically used the same method used by pod Pod's button labels thread 1. print the labels Draw your labels in your favorite program and print those on a transparency film (laser or inkjet, depending on your printer). Make sure you have at least 2 copy of each label, since you'll probably need to use 2 layers. 2. Roughly cut the label. 3. Merge the 2 layers. Pod's tutorial uses some sort of glue to secure the 2 layer of each label. In my case, I simply used some double sided tape. 4. Cut the label carefully cut the label to fit the push button 5. Insert the label. Insert the label in the push button and reassemble it. Here's a snapshot of one lighted translucent button. all right, my eyes are burning. Time to go to bed now... Jay :cheers: |

:o I love this project. Awesome work!!! I have a question - I'm contemplating adding the 7th neo-geo button to my next CP... will you use that button as the default "button 1" in all games other than 6-button fighters? So it would fire in Galaga, shoot the ball in Mr. Do!, jump in Donkey Kong, etc... what about 2 and 3 button games? |
